Windows 8.1 : Modern Applications and Cookie-Based Authenticated Proxies

I’ve been testing Windows 8.1 within the organisation for a few weeks – and have been experiencing issues with Modern (Metro) Applications when interacting with our zScaler proxy. The issue with this, amongst other cookie-based authenticated proxy servers, is that Modern Applictaions do not support the use of the users cookie to provide authentication to the proxy. Essentially we would see issues such as:

  • The Windows Store displays no images / complained about not being connected to the Internet
  • Application downloads would fail from the store
  • XBox Music and other streaming applications would play no content

For example:

 

 

The long and short of it is that you need to create an authentication bypass for a company-defined domain whitelist – this whitelist should contain:

{code lang:text showtitle:false lines:false hidden:false}account.live.com
w3.org
wustat.windows.com
login.live.com
.aspnetcdn.com
.ib.adnxs.com
.msftncsi.com/ncsi.txt
.s-msft.com
.s-microsoft.com
clientconfig.passport.net
.windowsupdate.com
.wns.windows.com
.hotmail.com
.microsoft.com
.outlook.com{/code}
